BRAKE-BEAM surron'r.

Application filed September 25, 1916. Serial No. 121,971.

To all whom it may come: n:

Be it known that I, J OSEPH W. WEINLAND, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Brake-Beam Supports, of which the following is a specifi cation.

My invention relates to railway car brakes and has particular reference to a novel emergency brake beam support. The construction here illustrated is intended as an improvement upon the construction shown in the patent to Elliott, No. 1,147 ,7 93.

A brake beam supporting means which provides for the suspension of a bar beneath the two brake beams has been found to be a most desirable and advantageous construction. However, it is necessary to provide for the displacement of the bar by a longitudinal movement in either ofv two directions and to that end fasteningdevices, in the form of keys or cotters have beenutilized. However, it has been found that the Wear due to the constant vibration causes the destruction of such fastening means. Not only that, but it is not uncommon that the key or cotter be lost or displaced by the workman when the bar has been removed, or that the workman fails to return the key to its proper position through neglect or oversight.

With the object in view of overcoming 'th objections referred to, I have provided automatic means on the'horizontal bar, or adapted to coeperate therewith, which means cannot become lost and may be; made of such size as not to be destroyed by wear due to vibration.

The invention will be more readily understood by reference to the accompanying drawings, wherein Figure 1 is a side elevation of a portion of a car truck, the side frame and wheels being shown in dotted lines, and the brake beam and spring plank being shown in section; Fig. 2 is a sectional view on the line 22 of Fig.1; Fig. 3 is a sectional view on the line 3-3 of Fig. 2, and Fig. 4 is an elevation of a slight modification in the construction shown in the preceding figure.

' In the drawings the side frame is indicated at 10. Connecting the two frames necessary to constitute a truck is a spring plank 11 in the form of a channel. Near each end the hanger. The shelf provides a wide hearing for the supporting member 14:. The construction of the hanger was not evolved by me, but will be claimed by another in a copending application.

The supporting bar 14 is in cross section in the form of an I-beam and is placed vertically, that is, with the-web thereof extending vertically. As a fastening means I employ spring fingers or catches15, riveted at 16 to the web of the bar and the points of which fingers or catches normally project outside a plane passing through the side edges of the flanges of the I-bea'm. By reason of this construction it will be seen that the beam maybe readily inserted by longitudinal movement into proper engagement with the hangers 12, a spring finger being depressed to the required extent. To remove the bar by a longitudinal sliding movement thereof, it is only necessary to de ress one of the springs 15.

In the modification shown in Fig. 4, the spring plank 17 and hanger 18 remain the same, In that instanceI have provided a leaf spring 19, which instead of being riveted to the bar'is riveted to the hanger, and

the lower end of which spring projects into the plane of the top of the bar. A notch 20 may be made in the top of the bar with which the spring may engage. The operation of placm and replacing the bar will be readily un erstood without further deconstructions herein illustrated. My invention contemplates the use of such devices and I therefore do not wish to be limited to the exact .forms here shown and described.

I claim 1. In an emergency brake beam support, the combination of a hanger, a bar supported by said hanger andlongitudinally movable into and out of engagement therewith and automatic means acting as a lock to prevent relative'movementof the hanger and bar, substantially as described.

Specification of-Jletters Patent. Patented Nov, 28, 1916,

2. In a car truck having frame members, the combination of a vertically disposed hanger engaging a frame member, a horizontally disposed bar engaging said hanger and spring means fixed to one of said members and automatically engaging the other thereof when the parts are in operative position, substantially as described.

3. In a device of the class described, the combination of a pair of depending hangers each having an aperture, a bar horizontally disposed and occupying the apertures in said hangers, and a spring fixed to said bar and adapted to automatically hold said bar when the same is in operative position, substan tially as described.

4. In a device of the class described, the

Copies of this patent may be obtained for combination of a hanger having an aperture, a bar adapted to be supported by said hanger and engaging said aperture, said bar 2-) ing such that said spring acts as a fastening 25 device, preventing longitudinal movement of said bar under normal conditions, substantially as described.
